Just made an 219HP engine (1100cc, octane 100 @ 2020 (tho i dont think it matters compared to 2012 atm…).
Forgot to save my screenprint, will make it again in a sec

5 valves gives more horsepower then 4 valves

Beat this
There is already a thread where you can share engines you have created with the community.
PS-A lot of people have beaten that number, and I’ve even seen someone with a 1.0L get up to 220BHP.
